Application filed September 30, 1907. V Serial No. 395,283.

g have invented certain-new and useful Imrovements in .Motor-Vehicles, of which the iiollowing is a specification. A

.In finlshing the `bodies of motor vehicles'it is customary to use a inetal strip or bead as a border to the Yvarious panels, such strip usually being'scgi'nental in cross section. lt has been customary to attach these beads to the bodies of 'motor vehicles by means of suitable nails havin heads which fit countersunkopenings in tie beads or by means of.

screws fitting such countersunk openings,

the heads of the nails or screws being afterwardsl filed to conform to the contour of the bead` In lnishin the bodies the beads are painted or ename ed arid'it has been'found that the severe strains to which automobile bodies are subjected almost invariably loosen the screws ornails or cause themto work with rcs ect to the beads, thereby producing craciis in the enamel at the joints beand thebead and disfiguring the vehicle.

The object-of my invention is to obviate these diiiiculties and I accomplish this object by countersinking the screw' holes in the beads to a depth greater than that of the i* screw heads and with a counter sink having a greater angle or wider pitch than that of the screw head, filling the countersunkhole with solder` or' other suitableffusible metal and finally shaping the solder to 'conform to the countour of the bead. By makingthe angle of the countersink. greater thanl that of the screw head', a portlon of the solder flows `under the head 0f the screwv and -thus solder in turn enters l,the slot in the screw head and otherwiseI attaches itself to the y screw, preventing the latten from turning.

Thus the button 'of solder and the screw are interlocked, each holding the other in'` place.' The invention will befully described in connection withl the accompanying "drawing,

inwhicln. l 4 l Figure 1 1s a s1de view ordlagram of a Ino- Zis asection on the linen 8; Fig.'3is an enlarged seat.

view of a portion 'of Fig.- 1, showing details of construction; Fig. 4 1s an enlargement of a portion vof Fig. 2; Fig. 5 is a section of the bead or trim; and Fig. 6 is a view similar to Fig. 4 showing a slightly modified arrangement of the invention.

Referring to the drawing, ldindi'cates tlie body of an automobile,1l the side door, 12 the back and. side arms of the rear seat and 13 the back and side ,arms-of the forward The body may be-constructed entirely ofv wood but it is customary to con struct such bodies Ofmetal plates secured upon a wooden frame, as4 hereinafter more particularly described. The mar ins of the ody portion are trimmed with a ead 14 to enhancejthe appearance of the vehicle and portions of the ody are sometimes divided inthe panels by such beads. -As heretofore stated ithas been found difficult to secure the bead to the bod in such a manner as to lv prevent the ename from cracking over or around the screws'or other fastening devices. To obviate this. difficulty and to more-sccurely hold the bead in place, I attach the same in the following' manner: The bead is bored at suitable intervals with holes 15 to receive screws and,` these holes -are countersunk with a wide-angled countersink forming conical openings 16, as shown in Fig. 5.

The angle of the .opening 16 should be greater than the angle or itch of the head of the screw 1-7 which is use to fastenthe bead to the frame 18 'of the body, thus leaving a space` under the screw head between said head and the wall of the opening 16, as shown in Figs. 4 and 6.A After the bead, thus pared, has been fastened to the body or l oor or other part to be trimmed by screws 17 the cavity 16 is iilledwith solder or other `suit able easily fusible metal or alloy 19, thev cavity and screw head being first treated y with a suitable flux ormaterial to cause the fusible metal to adhere. Sufficient heat Vis applied to cause the fusiblemetal toow aroundl the screw head andcom letely. ll thecavity.' -When cooled the surp us'fusiblef.

metalV is removed and .its surface finished thus providing an annular space between vthe' i screw head and the wall of said cavit ,.whilein Fig. 6 the screw is inclined, itsJhea resting -.with a le or other 'tool'toconform accul is anchored to the screw head and cannotk fall out even though it should become loose from the bead. `The button however will almost invariably adhere permanently to the bead, and perform the function of locking the screw against turning.

As shown in the drawing, the panels are covered with metal plates 20 which are se cured at their margins to the frame 18, by

screws or other suitable fastenings 21. The

beads are then placed over the metal plates.

and arranged to'cover the fastenings 21, thus serving the double purpose of a trimming for the body and for covering the fastenings 21 and preventing them from loosening or dropping out.

I am aware that it has been proposed to cover screw heads with cylindrical or other plugs inserted in the wood above the screw andbelieve that such devices have been used upon ordinary carriages; but the rough usage to which automobiles are subjected tends to loosen the screwsand loosen plugs of this character, thus cracking the enamel and d-is'figuring the vehicle. It will be understoodl thatthe bead or strip used in'c-arrying out my invention is made of metal to which a' fusible metal or alloy, such as solder will adhere.V I preferably use brass for this purose. -ifi/'hen a bead is put on according to themethod herein described and properly finished, therfastenings cannot be detected and the enamel presents a smooth unbroken p surface throughout the length of thebead.

Having described my .invention what I claim and desirev to secure by Letters Patont is,. -v

1. In a vehicle body, 'the combination with the body, of a metal bead or strip andl securlngscrews passingthrough said strip into the body'the said strip havingc'countersinks lar er than the screw heads, and fusible meta buttons filling said oountersinks, t

for the purpose set fort A 2. In a vvehicle body, the combination with the'body, of a metal bead or strip and V sensa? securing screws passing through said strip into the body, the saidstrip having countersinlrs larve-r than the screw heads, and fusi- .ble metall buttons filling saidV countersinks and extending under the screw heads, for the purposeset forth.

In a vehicle into the slots thereof, for the purpose set forth.

f4. In a vehicle, the combination with the' body, of a metal bead having countersunk screw holes, screws extending through said holes into the body, the countersinlrsin the bead having a wider pitch or angle than the pitch of the screw heads and being deeper than said screw heads, whereby s aces are created between the under sides of t iescrewheads in the walls of the countersinks, and fusible metal buttons filling said counterbody, the combination with the body, of a metal bead or strip and' sinks, including the s aces in and around the screw heads, thel sain buttons being finished ou their outer surface to conform to the beads;

5. In vehicle construction, the combination with the body frame, of metal vplates forming a sheathing on said frame, screws )assing through the margins of said lates for attaching the plates to the frame, eads covering said screws to hide the same and preventtheir displacement, and screws extending through the beads and the yplates into the frame, the beads hav-ing countersinks to receive the heads of 'said latter screws, said' countersinks having va reater angle or pitch than the screw heads an bein filled with fusible metal, whereby allof sai parts are securely and permanentlytconl nected together, for the purpose set forth.y

In testimony whereof I affix my signature in presence of two witnesses. A
